Newly-released photographs of the alleged Boston Marathon bomber show him emerging from a boat in a suburban backyard on the night of his arrest, face bloodied with a gun laser-sight aimed at his head.

The photos of Dzhokhar Tsarnaev, published by Boston magazine, were taken by state police and leaked by an officer who has since been reassigned to an overnight shift in a remote area of Massachusetts. Other photos show an injured Tsarnaev dropping to the ground, where policemen and medical personnel rushed to treat him.

Tsarnaev has pleaded not guilty to the April 15 attack, which killed three people and injured more than 260 others. His older brother and alleged accomplice was killed while fleeing from police.
